create a hash from an array in ruby

Question

I have an array in a specific order, and wish to create a hash with the odd numbered entries of the array as indexes and the even as values. This code does it perfectly, but leaves out one pair of values from the array.

    resolv_hash = Hash[*namerslv_array]
            puts "values in hash"
            resolv_hash.each do |key, array|
            puts "#{key}   " + array
            end

can anyone help with this please?

Answer 1

I think you want:

resolv_hash = namerslv_array.each_slice(2).to_h

Illustration:

>> array = [1,2,3,4,5,6,7,8,9,0]
>> array.each_slice(2).to_h
=> {1=>2, 3=>4, 5=>6, 7=>8, 9=>0}
